In daily life and industrial production, carbon monoxide (CO), as a colorless, odorless but highly toxic gas, often poses a serious threat to people's life and health. In order to effectively monitor and control the concentration of carbon monoxide, electrochemical carbon monoxide sensors came into being.

    Today, Tensensor will give you a detailed introduction to the principles and applications of electrochemical carbon monoxide sensors to help you better understand this technological guard.

Principle of electrochemical carbon monoxide sensor

    Electrochemical carbon monoxide sensor is a gas detection element based on electrochemical principles. When carbon monoxide gas molecules enter the sensor through a breathable membrane and come into contact with the surface of the sensing electrode, an electrochemical reaction occurs. Specifically, carbon monoxide is oxidized on the working electrode to generate carbon dioxide, electrons, and protons (hydrogen ions). At the same time, these electrons flow to the counter electrode through an external circuit to form a current. The magnitude of this current is proportional to the concentration of carbon monoxide, so the gas concentration can be determined by measuring the current intensity.

    There is a good linear relationship between the current output by the sensor and the carbon monoxide concentration, which makes signal processing and concentration reading simple and accurate.

Application of electrochemical carbon monoxide sensor

    Electrochemical carbon monoxide sensors are widely used in many fields, including civil fire protection, industrial safety, energy storage safety, etc., due to their advantages such as fast response speed, high sensitivity and low cost.

    In the field of civil fire protection, electrochemical carbon monoxide sensors are widely used in fire protection systems in homes, commercial buildings and public places. By monitoring the concentration of CO generated by the fire, fire hazards can be discovered early, and precious time can be gained for people's escape and firefighters' rescue, thereby effectively protecting people's lives and property.

    In the field of industrial safety, carbon monoxide is a common toxic gas that may be released into the air due to incomplete combustion. Therefore, electrochemical carbon monoxide sensors are widely used to monitor the concentration of CO in factories and workshops to ensure the safety of workers. This sensor can monitor the concentration of carbon monoxide in real time and accurately. Once the concentration exceeds the safety standard, it will immediately sound an alarm to remind workers to take necessary protective measures, thereby effectively avoiding the occurrence of carbon monoxide poisoning accidents.

    In the field of energy storage safety, electrochemical carbon monoxide sensors also play a vital role. When the battery packs of energy storage power stations are highly concentrated, they are easily affected by internal and external factors such as overcharge, overdischarge, overheating, and mechanical collision, which can lead to battery diaphragm collapse and internal short circuit, and then cause thermal runaway and fire. Carbon monoxide is one of the toxic gases that energy storage batteries will release before a safety accident occurs. Therefore, the application of electrochemical carbon monoxide sensors can achieve early warning monitoring, detect abnormal conditions in time and take measures, so as to effectively avoid the occurrence of fire accidents, which is very suitable for the field of energy storage fire protection.

    With the continuous advancement of technology and the enhancement of environmental awareness, the application scenarios of electrochemical carbon monoxide sensors are also expanding.

In the field of smart homes, this sensor can be integrated into gas water heaters with carbon monoxide protection and gas leak protection functions, and detect the carbon monoxide and methane content in the space in real time 24 hours a day. Once the gas concentration is detected to exceed the warning value, an alarm will be immediately issued to prevent carbon monoxide poisoning accidents through active leakage prevention.

In the field of smart cities, electrochemical carbon monoxide sensors can also be used to monitor carbon monoxide concentrations in urban environments, providing data support for urban planning and environmental protection.

    In addition, electrochemical carbon monoxide sensors also have broad application prospects in the fields of environmental monitoring and automobile exhaust monitoring.

    As an important part of modern science and technology, electrochemical carbon monoxide sensors play an important role in protecting people's life safety and health with their high sensitivity, rapid response and accuracy.

In the future, with the continuous advancement of technology and the continuous development of the market, the performance of electrochemical carbon monoxide sensors will continue to improve, and the application scenarios will be more extensive, bringing more convenience and safety to people's lives and work.
